Tornado chart is useful for those who want to analyze their data for better decision making.
It’s a useful tool for sensitivity analysis...
...but you can use it for comparison purpose as well.
It’s like a two-sided bar chart (looks like a tornado) where we have two data bars opposite to each other. It makes it easy to compare both of them. It’s a useful tool for sensitivity analysis.
According to Wikipedia
It’s a special type of bar chart in which data is sorted vertically from highest to lowest. With this type of shape, it looks like a tornado.
In Excel, there is no default option to create a tornado chart but we can use a bar chart and customize it accordingly.
So today, in this post, I’d like to share with you a 7-steps process to create a tornado chart in Excel.
So let’s get started.
Steps To Create a Tornado Chart
Here we are using following data table of two stores for comparing their product wise sale.
First of all, we need to convert data of store-1 into the negative value. This will help you to show data bars in different directions. Just multiply data with -1 or you can also use paste special option for this.
Now, insert a bar chart using this data table. Go to Insert Tab -> Charts -> Bar Chart. You will get a chart like below.
Select the axis label and open formatting options. Go to axis options -> Labels -> Label Position. Change label position to “Low”.
Next, you have to change axis position in reverse order. Go to Axis options -> Axis position -> tick mark “Category in reverse order”.
Next step is to change series gap and gap width. This will help to streamline data bars with each other. Go to series options -> Change series overlap to 100% and gap width to 10%.
Now, you have to change number formatting of the horizontal axis. Go to Axis Options -> Number -> select custom -> paste following format and click add.
Same like this you have to change the format for data labels for store-1. Go to label options -> Number -> select custom -> paste following format and click add.
Congratulations, your tornado chart is ready.
